Ricoh/Pentax has interesting products in the new trade show. I remember when sports and news photographers preferred bigger film plate cameras to the much smaller 35 mm (FF) film cameras. Size seems to be just as important in digital photography, because of the comments of many forum posters. Personally, I'm comfortable with ASCP size sensors, and at this time, I have no desire to switch to gear with the slightly larger full frame size sensors . However, I do still admire the depth of tone and range of greys from larger mid-size B&W film, which digital can't match. Therefore, I would like to try out a Pentax 645D. When I heard that the Pentax 645D has been updated, and possibly competive with FF in price, I was very interested.
